1. Genetics: more recent scholarship, has found that genes are likely to play a role, though exactly which genes are involved have yet to be determined. (Laura Angers)

2. Personality traits:  neuroticism, perfectionism, and impulsivity are three personality traits often linked to a higher risk of developing an eating disorder. (Alina Petre)

3. Social pressures from the media: include perceived pressures to be thin and cultural preferences for thinness. (Alina Petre)

Many people with bulimia also restrict what they eat during the day, which often causes more bouts of bingeing and purging. During these episodes, it is normal for you to eat a large amount of food in a short time, and then try to get rid of the extra calories in an unhealthy way.

Eating disorders including anorexia nervosa, bulimia nervosa, and binge eating disorder have the highest mortality rate of any mental illness.

Sadly, the persistent myths surrounding eating disorders make it harder for people with eating disorders to get the help needed to fully recover.  

Eating disorders are often dismissed as illnesses of choice and vanity, or the consequence of a deliberate adoption of an extreme diet. However, these disorders have far more complex origins.

This rumination typically occurs within the first 30 minutes after a meal. Unlike medical conditions like reflux, it’s voluntary.

This disorder can develop during infancy, childhood, or adulthood. In infants, it tends to develop between 3–12 months of age and often disappears on its own. Children and adults with the condition usually require therapy to resolve it.

For instance, the affected person may eliminate entire food groups, fearing they’re unhealthy. This can lead to malnutrition, severe weight loss, difficulty eating outside the home, and emotional distress.
